Hi Guys/Girls,
I have a maths exam tomorrow and there is a chance I could be asked to prove the cosine rule or sine rule.
Well I have a simple proof of the sine rule but cannot find a simple one for the cosine. They all seem very advanced.
Would anybody have a straightforward proof for...
I think I may be getting it.. what variables would you introduce then?
n: number of boxes
e: number of empty boxes
I need to discover an invariant for this.
I've tried modelling a move: fill 1 box
e:= e+7
n:=n+8
what possible invariants can I get from this? TBH I'm not sure if I...
Thanks for the quick reply Feldoh,
I like what you're saying..it makes sense but I have to come up with an invariant. If I don't then I will get no marks at all
Hi, I've been given this problem for homework but I am completely baffled..I can't even translate the first move into values on the variables..
Any help on this would be greatly appreciated..Sorry if I'm being a bit abrupt here but my head is fried at this stage..
Thanks Guys...
